This was not at all on "the list" 
No stress ! Nobody missed the restock ! 
I was bored during site migration and started browsing the thread....which lead me to a stockist 
Anyway....is the fit "right" for you guys? Pictures are with t-shirt only but I'll probably wear this one more with a sweat or UHF added.
I may manage M over this L for P2P, waist and opening, but fear the centimeters lost on shoulders and sleeves will make the sleeves too short.
It arrived 
I think the sizing is top notch ! Thx here also to @JoshC for having measured the remaining shirts in my size to find me a perfect match 
Always some issues for me with sleeves length, but here they fit perfectly imo, and the slightly shorter length versus the charts is really to my liking . Now I really need to wash this one carefully as there isn't really room for any shrinking.
I still haven't any denim shirt, not even a black shirt, and am also a CPO virgin.
This might be the one I choose to come out of this uncomfortable situation
Originally ordered the Medium that was really nicely fitting but it could not have moved one mm with washing, so I did take the Large at the end, which I finally prefer. Much more room, more comfy, and still a nice look, in my opinion at least 
About the collar, at the end it does not bother me, but it's definitely not tight-tight; design choice I guess, and again it looks good I think because the collar is really thick.
Edit: sorry for the not so good picture quality, should also clean that mirror 
@all: Thanks for all the answers ! I think I overthought this too much....the jacket is reaaaaaally great.
I wore it today, and all "worries" did vanish 
Really impatient to see how it will develop over the years.
@ZackB more fomo for you man 
A bit on the long side for me, but the fabric is cool and other measurements are great and fitted.
Also very much like the "big" collar.
X-posting with the IHSH-420-PIN thread since there isn't much picture material for this one.
Finally started to wear this one a bit more....really cool and stylish imo
Tight indeed in the chest when closed but the small P2P + length allows for this particular trim fit where the jackets opens more the more it goes down on the body.
Goes also really well thus with untucked shirts that would go too much lower than the jacket (personal taste ofc), thanks to the "extra" length
Very cool shirt ! Color goes well with almost everything (not duck for once )
Size small was fitted like a normal shirt let's say, but sleeves were much too short for me, and layering would have been impossible.
Size medium (on pictures) is perfectly comfy; it's more roomy then what I'm used to in waist and opening, but I dig it !
I think you need to go with the intended fit for this one.
Picture with closed shirt is with only a T under, the ones with the shirt open are with a sweatshirt (not a IH-thick one 
)
@tk303 The lining is not that thick imo that it matters that much with sizing correctly.
But the denim is quite stiff, and if you're like me, a bit between 2 sizes, you might need to decide for a certain look.
For me at the end, I prefer a slightly bulkier look with this jacket, it being overall a more cold weather jacket that might need to accommodate UHF, etc.
I tried with a M, and even though it did fit, I felt restricted, and most importantly for me, I kind of lost the cozy feeling of a nice warm winter jacket.
Plus you can always shrink it a bit if necessary (CTRL-F the thread to find a user at least who did post shrink results).
Here is a picture with a IH shirt + T-shirt under to give you an idea (same look with a UHF but I took the picture with this one). I'm 180cm and now around 73 kg.
Added bonus for me but I don't like when shirts exceeds too much the jacket length in general, so the slight over-sizing really helps here.
@Denimminer Perfect sizing imo 
About the fabric, I also had this initial thought about the thickness, but I have weighted the shirt against an aspero one I have from around same measure, and it's about the same.
But it feels lightly thinner to me too.
I will tell you what the guys from IH would: Just measure your best fitting UHF and compare the measures
Products from IH vary too much in style/size/etc. to stick on a certain size
If you have a shop at 1h I would do it ! For me the closest is 6h to London 
@Biecher Hey ma, no problem, I'm 180 cm and 74kg for the moment

@AdamJ Many thx for the info
@AdamJ Will those get a restock this year still ?
Joined da slub-club too, patiently waiting now 
ouch, this one is on my want list, but I had kind of hoped for once that measures wouldn't be great so I could push this back to the next release, but size 33 is quasi a perfect match for me
@Shane-B Thanks Shane for confirming again, I suspect this shirt will be a great success
@AdamJ Thanks for clarifying Adam
